■Sensor detectio n information
●The sensor’s detection areas are limited
to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the sur-
rounding environment may affect the
ability of a sensor to correctly detect an
obstacle. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this
problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is
frozen the screen may show an abnormal
display, or obstacles may not be
detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud
noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender
pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• A backlit license plate, license plate holder, etc., are installed.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is
not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low- ered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are
instances in which, because of their shape,
signs and other objects may be judged by a
sensor to be closer than they are.
●The shape of the obstacle may prevent a sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that
absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections pro- jecting outwards in the direction of your
vehicle
●The following situations may occur
during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• Obstacles may not be detected if they
are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at
slow speeds, there is a possibility that the
obstacle will come within the sensor’s
detection areas befo re the display is
shown and the buzzer sounds.
• Thin posts or object s lower than the sen-
sor may not be detected when
approached, even if they have been
detected once.
• It might be difficult to hear beeps due to
the volume of audio system or air flow
noise of the air conditioning system.

WARNING
■When using the intuitive parking
assist
Observe the following precautions.
Failing to do so may result in the vehicle
being unable to be driven safely and pos-
sibly cause an accident.
●Do not use the sensor at speeds in
excess of 6 mph (10 km/h).
●The sensors’ detection areas and reac-
tion times are limited. When moving
forward or reversing, check the areas
surrounding the vehicle (especially the
sides of the vehicle) for safety, and
drive slowly, using the brake to control
the vehicle’s speed.
●Do not install accessories within the
sensors’ detection areas.
NOTICE
■When using intuitive parking assist
In the following situations, the system
may not function correctly due to a sen-
sor malfunction, etc. Have the vehicle
checked by your Lexus dealer.
●The intuitive parking assist operation
display flashes, and a buzzer sounds
when no obstacles are detected.
●If the area around a sensor collides
with something, or is subjected to
strong impact.
●If the bumper collides with something.
●If the display shows continuously with-
out beeping, except when the buzzer
mute switch has been turned on.
●If a display error occurs, first check the
sensor.
If the error occurs even if there is no
ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of water or
steam to the sensor area.
Doing so may result in the sensor mal-
functioning.

*:If equipped
The system operates in the following
situations when an obstacle is detected
in the traveling direction of the vehicle.
■The vehicle is driven at low speeds
and the brake pedal is not
depressed, or is depressed too late
■The accelerator pedal is depressed
too far
■When the shift lever is mistakenly
in D and the vehicle moves forward
Parking Support Brake func-
tion (for static objects)*
When a collision may occur with an
obstacle while parking or traveling
at low speeds, when the vehicle
suddenly moves forward due to
mistaken accelerator pedal opera-
tion, or when the vehicle moves due
to the shift lever being in the wrong
position, the sensors detect obsta-
cles to the front or rear in the travel-
ing direction of the vehicle, and the
system operates to lessen impact
with obstacles such as walls, and
reduce resulting damage.

WARNING
■For safe use
Do not rely solely upon the system. Rely-
ing solely upon the sy stem may lead to an
unexpected accident.
●Driving safely is the sole responsibility
of the driver. Pay careful attention to
the surrounding conditions in order to
ensure safe driving. The Parking Sup-
port Brake function (f or static objects)
can provide support to lessen the
severity of collisions. However, it may
not operate depending on the situa-
tion.
●The Parking Support Brake function
(for static objects) is not a system
designed to completely stop the vehi-
cle. Furthermore, even if the Parking
Support Brake function (for static
objects) is able to stop the vehicle,
brake control is canceled after
approximately 2 seco nds, so depress
the brake pedal immediately.

■Preventing sensor malfunctions
●If the area around a sensor is subjected
to an impact, equipment may not oper-
ate properly due to a sensor malfunc-
tion. Have the vehicle inspected by
your Lexus dealer.
●When using a high-pressure washer to
wash the vehicle, do not spray water
directly on the sensors. The sensors
may not function properly if subjected
to an impact from strong water pres-
sure.
●When using steam to wash the vehicle,
do not direct steam too close to the
sensors. The sensor s may not function
properly if subjected to steam.

■Operation starting conditions
When the PKSB OFF indicator is not illumi-
nated or flashing ( P.233, 370) and all of
the following conditions are met, the system
operates.
●Hybrid system output restriction control
• The Parking Support Brake function (for static objects) is on.
• The vehicle speed is 10 mph (15 km/h) or
less.
• There is an obstacle in the traveling direc- tion of the vehicle (6 to 13 ft. [2 to 4 m]
ahead).
• The system determined that a stronger- than-normal brake operation was neces-
sary to avoid a collision.
●Brake control
• Hybrid system output restriction control is being performed.
• The system determined that an emer-
gency brake operation was necessary to
avoid a collision.
■Operation ending conditions
In any of the following situations, the system
stops operating.
●Hybrid system output restriction control
• The Parking Support Brake function (for static objects) ha s been turned off
(stopped).
• The collision became avoidable with nor- mal brake operation.
• The obstacle is no longer in the traveling direction of the vehicle (6 to 13 ft. [2 to 4
m] ahead).
●Brake control
• The Parking Support Brake function (for
static objects) ha s been turned off
(stopped).
• Approximately 2 seconds elapsed after the vehicle was stopped by brake control.
• The brake pedal was depressed after the vehicle was stopped by brake control.
• The obstacle is no longer in the traveling
direction of the vehicle (6 to 13 ft. [2 to 4
m] ahead).
■Sensor detection range
The detection range of the Parking Support
Brake function (for static objects) differs
from the detection range of the clearance
sonar ( P.230).
Therefore, even if the clearance sonar
detects an obstacle and provides a warning,
the Parking Support Brake function (for
static objects) may not start operating.
■Obstacles not detect ed by the sensors
The following obstacles may not be
detected by the sensors.
●Objects such as people, cloth and snow,
that are difficult for sonic waves to reflect
off of. (In particular, people may also not
be detected depending on the type of
clothing they are wearing.)
●Objects not perpendicular with the
ground, objects not at a right angle to the
traveling direction of the vehicle, uneven
objects or waving objects
●Low objects
●Thin objects such as wires, fences, ropes
and signposts
●Objects that are extremely close to the
bumper
■Situations when the system may operate
even though there is no possibility of a
collision
In the following situations, the system may
operate even though there is no possibility
of a collision.
●Environmental influence
• The vehicle is driven on a narrow road
